Description
Technical field
The present invention relates to be used for the tension mask of color cathode ray tube, more particularly, relate to a kind of tension mask that has the edge bluff piece.
Background technology
Traditional mask color cathode ray tube generally includes and is used for producing three electron beams and electron beam is mapped to electron gun on the screen of cathode ray tube.Screen is positioned at the inner surface of cathode ray tube face screen and is made of three kinds of phosphor elements arrays that can send different colours.When making cathode ray tube, shield the border that the shadow mask of arranging is used for demonstrating screen array and limits array with respect to face.In cathode ray tube work, shadow mask places between electron gun and the screen exactly to duplicate the source position of masking process.Shadow mask serves as the parallax baffle that covers screen effectively and makes the transmission part of electron beam can excite the phosphor elements of respective color on the cathode ray tube screen.
In traditional cathode ray tube, but shadow mask is a circular arc sheet metal that its shape of self-sustaining is consistent with the cathode ray tube screen inner surface, is bearing on the shadow mask frame.What another group generally was used for CRT shadow mask is tension mask.The example of tension-type shadow mask is connecting rod and wire harness tension mask.The wire harness tension mask comprises some tensions and is welded on pencil of parallel lines on the rigidity shadow mask frame.The wire harness of tension provides the pretension on the vertical direction, thereby guarantees that the slit that forms between the wire harness can keep aiming at the phosphor elements on the screen.In order to keep the tension force of shadow mask, shadow mask must be fixed on the durable framework.
Can find that in traditional cathode ray tube wire harness is fixed on the framework with two kinds of different forms.Wherein a kind of form comprises the solid border on the framework of being welded on of the center gap of surrounding shadow mask.The solid border of shadow mask constitutes the border of cathode ray tube screen array again as the optical edge that forms the matrix black surround.Second purposes of the solid border of shadow mask is to be used for providing electronic shield to reduce undesirable electron scattering when vertically passing scans at the edge in effective scanning zone.Second kind of form of fixed beam comprises every independent shadow mask wire harness is fixed on the framework.Because the cathode ray tube pattern is attractive in appearance, surperficial radian is limited or do not have a lot of reasons such as radian fully, thereby the tension mask of these two kinds of forms can be satisfactory.
Find that also the most handy different material of shadow mask and shadow mask frame makes, to reduce the weight of needed shadow mask tension force and shadow mask-frame assembly.In commercial tension mask cathode ray tube, the solid border of shadow mask is welded on the shadow mask frame.The consequence that solid border is welded on the framework is, when shadow mask and framework have different thermal coefficient of expansions, in the cathode ray tube heat treatment process, the solid border distortion can occur along the pad of shadow mask and framework, thereby make the live part of shadow mask produce permanent deformation.This distortion causes people to attempt individually shadow mask wire harness (or other etching shadow mask part) being fixed on the shadow mask frame, does not wherein have the shadow mask solid border and is fixed on the framework.Regrettably, the fixing separately of shadow mask wire harness also has problem, because wire harness tends to be subjected to displacement owing to the impetus of welder in welding process.Exist the technological problems on the framework except wire harness is fixed to separately, lacking the shadow mask solid border also brings and makes us the place that can not be satisfied with, because frame not only conduct forms and limits the optical edge of matrix black surround and screen array, but also can collide the stray electron that produces on the shadow mask frame side by the block electrons bundle.Therefore, require a kind of shadow mask wire harness indeformablely can being fixed to separately on the shadow mask frame of invention, also provide simultaneously as matrix and the optical edge of covering, and the shielding of the border of stray electron baffle plate.
Summary of the invention
The invention provides a kind of tension mask that is used for cathode ray tube.This tension mask comprises that both sides are fixed with framework and some spaced apart parallel wire harness that extends of suspending wall part between the suspending wall part of framework.The edge bluff piece is fixed on the wire harness along the edge of framework suspending wall part, so that carry out follow-up welding job.Make edge bluff piece and each wire harness end form clamping relation, thereby make wire harness be fixed on suspending wall part with predetermined spaced relationship.

Embodiment
Fig. 1 shows a kind of traditional cathode ray tube 10, and its glass bulb 12 comprises rectangular surfaces screen 14 and bores 18 necks that are connected 16 by the rectangle glass.Internal conductive coatings (not shown) on the glass cone 18 extends rearward to neck 16 and extends to forward on the face screen 14 from anode button 20.Face screen 14 comprises viewing screen 22 and is sealed to periphery flange or sidewall 24 on the glass cone 18 with glass dust 26.The inner surface of viewing screen 22 is provided with tricolour phosphor screen 28 (not shown microstructure).Fluorescent screen 28 is line-screens that comprise many screen elements, these screen elements are made up of the fluorophor striped R, G, the B that send out the red, green, blue color respectively, and by three stripeds or ternary colo(u)r group or pixel arrangement, each group comprises the fluorophor lines figure of each color in the three primary colors.The fluorophor lines are parallel to the minor axis Y of cathode ray tube haply.As in common knowledge in the art, the relatively thinner extinction matrix (not shown) crossover of at least a portion fluorophor striped and preferably.
Shadow mask-frame assembly 30 is by 28 one-tenth predetermined spaced relationships and removably fixing of conventional method and screen.As shown in Figure 2, shadow mask-frame assembly 30 comprises the tension mask 32 that is fixed on the framework 34.Tension mask 32 can be to have the shadow mask that friction connects wire harness tension mask, wire harness tension focus mask or other similar structures known in the art of damping wire.According to the present invention, tension mask 32 comprises the effective slotted section that contains some parallel spaced apart wire harness 44.Many elongated gaps 46 between wire harness 44 are parallel to the minor axis Y of tension mask 32.During cathode ray tube work, electron beam passes the slit 46 in the live part.The lateral dimension of every wire harness 44 or width can be equate or be designed to gradually change.For example, the width of wire harness can be approximately 0.55 millimeter (21.5 mil).The width in slit 46 equally also can be equate or be designed to gradually change.For example, the width in each slit can be approximately 0.11 millimeter (5.5 mil), and is parallel to cathode ray tube minor axis Y haply.
The electron gun 38 that with dashed lines schematically shows in Fig. 1 is installed in the neck 16 between two parties, can produce three parallel electron beam (not shown), central beam and two lateral bundles or external beam, these electron beams arrive screen 28 along the slit that convergence path passes in the tension mask 32.
The framework 34 that is used for supporting tension mask 32 is shown in Figure 2, comprises four limits: two long limit 40 and two minor faces 42 that are parallel to cathode ray tube minor axis Y that are arranged essentially parallel to cathode ray tube major axis X.Each long limit 40 all comprises the suspending wall part 52 that is fixed to minor face 42 ends.Though in the embodiment of the invention of being introduced, used framework 34, should know that the tension frame of many other types also can be used the present invention.
Be clearly shown that in Fig. 2 and 3 some wire harness 44 extend on two suspending wall parts 52 from live part, and be positioned between edge bluff piece 56 and the suspending wall part 52 by pad 58.Such as forming the sealing wire 62 that a succession of pad 58 constitutes with wheeled resistance welder or by other welding method such as laser welding.Be welded on the wire harness and along the edge bluff piece 56 at framework suspending wall part 52 each edge and form clamping relation, thereby wire harness 44 is fixed on the suspending wall part 52 with predetermined spaced relationship with each wire harness end.
In a preferred embodiment, suspending wall part 52 and edge bluff piece 56 are made by high thermal expansion coefficient (CTE) material such as low-carbon alloy steel or other ordinary steel that is fit to.In contrast, shadow mask wire harness 44 usefulness low thermal coefficient of expansion materials are made.Iron-nickel alloy such as INVAR (trade mark registration number #63,970), or other any similar material with low thermal coefficient of expansion (CTE) can use.When the low-thermal-expansion shadow mask that has solid border is fixed on the high thermal expansion framework, the cathode ray tube heat treatment meeting of carrying out under temperature can be up to 450 degrees centigrade is extended the solid border zone of shadow mask non-resiliently, thereby shadow mask produces distortion after cooling.Do not have at shadow mask under the situation of solid border, compare with the low-expansion coefficient tension mask 32 that has solid border, edge bluff piece 56 can adapt to the bigger expansion of high expansion coefficient framework 34, unlikelyly the permanent deformation of shadow mask frame occurs and makes shadow mask wire harness 44 produce significantly displacement.Edge bluff piece 56 generally obtains this effect by the material that is similar to thermal coefficient of expansion and framework, thereby avoids producing heat treated the time distortion.Therefore, by shadow mask wire harness 44 being fixed to separately on the suspending wall part 52 of framework 34, the lateral expansion of tension mask 32 is to be controlled by the lateral expansion of framework 34.For example framework 34 and edge bluff piece 56 can be made with the low-carbon alloy steel of thinking the high thermal expansion coefficient material, and its thermal coefficient of expansion is 120 to 160 * 10
-7In/℃ the scope.In this case, be to use low thermal coefficient of expansion material such as thermal coefficient of expansion even work as tension mask 32 9 to 30 * 10
-7When the iron-nickel alloy material the within/℃ scope is made, can not form distortion yet.
Shown in Fig. 3 and 4, tension mask 32 is made of the flat thin slice of the iron-nickel alloy that is etched into some wire harness 44.Mode with parallel spaced apart is in line wire harness 44 at the top of suspending wall part 52.By tension wire harness 44, such as to shadow mask 32 centers extruding suspending wall part 52, perhaps pass through other any known method in the art, can on wire harness 44, obtain pretension.At every end of framework 34, edge bluff piece 56 is installed on wire harness 44 ends and with the outer rim of suspending wall part 52 and aligns.Edge bluff piece 56 contacts with wire harness 44 and extends to the center of tension mask 32, makes the inner edge 54 of edge bluff piece 56 stretch out the inner edge 57 of suspending wall part 52.Under edge bluff piece 56 was fixed on situation on the wire harness 44, welder moved along the end face of edge bluff piece 56, by pad 58 edge bluff piece 56 and wire harness 44 is fixed on the suspending wall part 52, thereby machines tension mask 32.In welding process, bluff piece 56 protection wire harness 44 in edge make because harmful wire harness displacement that the impetus of welder such as wheeled resistance welder or similar devices causes reduces to minimum.In one embodiment, frame 56 and shadow mask wire harness 44 form the prepackage accessory, wherein edge bluff piece 56 was fixed on the wire harness 44 with adhesive before welding exactly, thus the accurate location of further guaranteeing wire harness 44, and make wire harness 44 can not produce displacement because of the welding action.Acrylic resin, epoxy resin or silicate binder can be applied to this purposes.
In last cathode ray tube assembling process, when face screen 14 was coupled together with tension mask 32, tension mask 32 was installed in from face and shields on the 14 extended post bolt (not shown).Electron gun 38 produces electron beam, and in fact its deflection center overlaps basically with the path that the light source of generation on screen 28 and location fluorophor striped is followed.Utilize matrix and masking methods in common knowledge in the art, edge bluff piece 56 not only constitutes the periphery in the matrix method but also defines fluorophor striped final position in vertical direction.
